Specification of Letters Patent.

Application filed February 4, 1919. Serial No. 274,972.

To all 11 /1 om. it may concern:

Be it known that we, Josnrn HIGGINSON ARUNDEL, subjects of the King ofGreat Britain and Ireland, and residents of Sovereign lVorks, Stockport,in the county ofChester, England, have invented certain new and usefulImprovements in Apparatus for RaisimrLiquids, of which the following isa specification.

This invention relates to apparatus for raising liquids and moreparticularly to suction operated devices for supplying fuel to internalcombustion engines. lVith such devices, it is usual to employ anintermediate high level vessel into which the fuel is drawn by suctionfrom the main fuel tank and from \vhichit is discharged through anonreturn valve by atmospheric pressure ora pressure greater thanatmospheric.

The invention comprises the combination with the vessel into whichliquid is drawn by suction and from which it is discharged byatmospheric pressure, or a pressure greater than atmospheric, and with acontinuously open suction connection, of a positively mechanicallyoperated pressure control valve for placing the said vesselintermittently under pressure by overcoming the effect of the suctionaction at regulatml intervals.

The accompanying drawing shows a: vertical sectional view of theintermediate high level vessel and its connections for placing the samein communication with discharging pressure.

In the apparatus as illustrated in the accompanying drawing, we providethe fuel inlet a. to the intermediate vessel 7) with a float controlledvalve 1: so that such inlet is closed when the level of liquid in thevessel reaches a predetermined' amount. The suction connection (.l isadapted to he continuatmospheric or other pressure connection e iscontrolled by a pin cock or timed valve f positively operated through amechanically rotated wheel as for any suitable mechanism. Preferably,the suction connection is of small cross sectional area as shown andleads to the atmospheric, or other pressure pipe or connection which isof relatively large bore With this arrangement, when the air valvecontents.

f is open, the amount of air which can pass the air valve is suflicientnot only to neutralize the suction action in the air pipe 6 but also toproduce the desired pressure in the intermediate vessel b fordischarging its air from the air pipe and does not draw off carburetedor partly carburetcd airsuch'as would be the case if independent air andsuction pipes extended to the intermediate vessel 6, and the suctionpipe was continuously open. We may, however, employ this latterarrangement, butwe prefer the previously described arrangement orconstruc tion. The float controlled prevents flooding of the saidvessel. The non-return valve it controls the flow of liquid from thevessel 6.

aving now described our invention what we claim as new and desire tosecure by Letters Patent is 1. In apparatus for raising liquids, thecombination with a vessel for the reception and distribution of theraised liquid of an inlet for the liquid, a valve for closing saidinlet, a float for opening and closing said valve, an outlet for theliquid, a valve for closin said outlet, an inlet for admitting air tosaid vessel, a continuously open suction pipe connected to said airinlet, a valve for opening and closing said air inlet, and mechanicalmeans, operating independent of said float, for intermittently actuatingsaid air inlet valve,
